Patent EP-0463096-A1 (EP)
Inventor: BRAMLETTE TILLMAN TAZWELL
IPC: F23C15/00
Filed: 1990-03-16
Abstract: Dans le procédé et l'appareil décrits, qui servent à moduler les caractéristiques de combustion d'une chambre de combustion à pulsation (20), les caractéristiques de mélange des réactifs de combustion et des produits de combustion sont modulées en fonction de la géométrie (22) de l'entrée de la chambre de combustion. La géométrie (22) de cette entrée peut être fixe ou variable, de façon à permettre la modulation des caractéristiques de mélange. Une boucle de réaction (44, 48) peut être utilisée pour détecter les caractéristiques de combustion réelles et ensuite pour faire varier la géométrie (22) de l'entrée, pour permettre l'obtention des caractéristiques de mélange désiré nécessaires pour produire les caractéristiques de combustion désirées. Dans un mode de réalisation préféré, le temps de mélange des réactifs et des produits de combustion est proportionné au rapport entre le rayon de l'orifice d'entrée et la vitesse d'injection. Divers modes de réalisation se rapportent à la variation du débit de masse des réactifs, variation qu'on obtient tout en maintenant constant le rapport rayon/vitesse.

Abstract: L'invention se rapporte à un procédé de production d'articles façonnés dérivés de l'amidon et, plus particulièrement, à un procédé de production de films dérivés d'un amidon à haute teneur en amylose. Ce procédé consiste à préparer un bain de fusion chaud en chauffant sous pression une composition comprenant une substance à haute teneur en amylose, ou un dérivé de cette substance, et suffisamment d'eau pour former un bain de fusion homogène, permettant l'extrusion ultérieure d'un article façonné. Le bain de fusion chaud est soumis à une pression atmosphérique ou sous-atmosphérique immédiatement avant ou pendant l'extrusion, de façon à extraire l'eau du bain de fusion chaud avant la formation de l'article façonné. La substance à haute teneur en amylose est de préférence dérivée des hybrides de maïs 55/77 ou 65/88 élaborés par la société Goodman Fielder Mills Pty. Limited. Les films dérivés de l'amidon, qui sont produits par ce procédé, sont particulièrement appropriés pour être utilisés dans des stratifiés à barrière d'oxygène et comme films du type paillis biodégradable.

Abstract: L'adjonction à des polystyrènes à résistance élevée aux impacts de quantités efficaces de polystyrènes bromés à faible poids moléculaire permet d'obtenir de manière inattendue une bonne rétention des propriétés des polystyrènes en même temps qu'une propriété ignifuge voulue, par exemple UL-94 VO. Par contraste, des polymères de styrène bromé de poids moléculaire élevé (ayant un degré de polymérisation égal à 2000) ne transmettent pas à des polystyrènes à résistance élevée aux impacts une bonne qualité de rétention de propriétés telles que la résistance aux impacts et la dureté. Le degré de polymérisation des polystyrènes bromés décrits est généralement compris entre 3 et 20 environ et leur halogénation peut varier considérablement. Ces polystyrènes à résistance élevée aux impacts, mélangés à ces polystyrènes bromés à faible poids moléculaire, peuvent être aisément traités par des équipements classiques.

Abstract: Un système de stockage de données insensible aux défaillances comprend un ensemble de puces mémoires disposées en une pluralité de rangées et de colonnes, chaque rangée de puces mémoires CO à CN possédant une puce de réserve CS. Chaque puce comprend un ensemble d'adresses de mémoire dont quelques-unes peuvent être défaillantes. Pendant la lecture et l'écriture simultanées des données par l'intermédiaire de lignes de données DO-DN aux puces respectives, une topographie MAP identifie toute puce présentant un défaut à l'adresse indiquée (p.ex. dans la colonne adressée) et raccorde la ligne de données à une adresse sans défauts dans la puce de réserve. Les adresses logiques des puces sont désalignées de façon différente l'une de l'autre par rapport à leurs adresses physiques, de sorte qu'il n'y ait aucun défaut coïncident dans les puces différentes. Une seule puce d'une rangée présente un défaut dans les colonnes adressées simultanément dans les puces respectives de cette rangée.

Abstract: A magnetoresistor (10) includes a thin film (14) of a degenerately-doped semi-conductor material extending between conductive contacts (18,20) at opposite edges of the film (14). The film (14) has a plurality of openings (22) therethrough which are arranged in spaced parallel rows with the openings (22) in each row being between two openings (22) in the adjacent rows. This forms the film (14) into two set of paths (24,26) which extend around the openings (22). The openings (22) are selected to be of a size such that, when a magnetic field is applied perpendicular to the film (14), the electrical resistance of the magnetoresistor (10) increases because electron flow through the film (14) between the contacts (18,20) must be in a substantially circular path around the openings (22).

Abstract: A mailing envelope (10) of tear-resistant sheetstock can be easily torn open by forming a pair of closely spaced parallel cuts (16,17) through the sheetstock and bonding over the cuts a length of reinforcing tape (18) that has good resistance to impact, good longitudinal tensile strength, and readily tears longitudinally while being highly resistant to transverse tearing. When the reinforcing tape is bonded to an inner surface of the envelope and is cut at one end coincident with the cuts in the envelope, that end of the tape serves as a pull tab by which a strip of the tape can be pulled through the envelope to open it between said parallel cuts.

Abstract: When controlling a travelling body so as to move forward the travelling body along the predetermined route, the distance and direction of deviation of a body of the travelling body from the predetermined route are measured, the above measured distance and direction of deviation of the body from the predetermined route are inputted as an observed value into an antecedent operation part in which the membership functions corresponding to distances of deviation of the body from the predetermined route are prestored. Then an operation of grade at the antecedent, namely a degree that an operator has a feeling that the above deviation is small or medium or large is performed. An operation of manipulated value in the consequent is performed by inputting the obtained grade into a consequent operation part in which the membership functions corresponding to manipulated values are prestored. The obtained manipulated value is outputted into the steering means. The steering means is controlled according to the manipulated value. 
     By means of the above mentioned method, an operator can automatically control the travelling body so as to move forward along the predetermined route without the help of veteran operator.
